I'd recommend grabbing a trial account if you have an app to build anytime soon.
Do you think that some form of dynamic time warping algorithm, performed on the data of each distinct group, could help give a better overall view of that group's behavior in a static heatmap image? Presuming participants share similar scanpaths within a group.
Just a thought, I understand the data may be too noisy / have too much variance for this to work in practice.
Modern eyetracking solutions can be quite accurate. I've used SR Research's Eyelink II [1] and have seen results from Tobii [2] eye trackers that are impressive too, considering their passive nature.
During my final year project for my BSc, I tried to address the problem of losing the temporal data from eye tracking in heatmaps with an accelerated replay, heatmap animation. Here's an example:
